Arsenic is a compound that occurs naturally in very low concentrations. Arsenic blood concentrations in healthy adults are Normally distributed, with mean u = 3.2 micrograms per deciliter (ug/dl) and standard deviation o = 1.5 ug/dl. What is the range of arsenic blood concentrations corresponding to the middle 90% of healthy adults? Use Table B or technology to find the proper values. (Enter your answers rounded to two decimal places.) from: ug/d1 to: ug/d1
